Duplicating placemarks is ONLY good for backup, problematic for anything else

Which products are affected?

Google Earth, Google Earth Pro, Google Earth Plug-in, Google maps

What steps will reproduce the problem?

1. Duplicate any placemark, not for backup, but for use in similar placemark 
formatting, etc. 
2. Rename duplicate, add new description and html, POV, etc.
3. Duplicate still mirrors original, sometimes in description, but mostly in 
KML file code, where one sees the original placemark ID still intact

What is the expected output or behavior? What do you see instead?

One would hope you could use the duplicate as a template, to create similarly 
formatted placemarks. Instead it carries the code ID of the original, causing 
all kinds of problems. You should let people know that duplication is not 
recommended, except for backup purposes ONLY.

What application versions (if any) are you using?

Mac OS 10.6.6; Google Earth Pro 6.0.1.2032 (beta) 

Which operating systems (and/or relevant web browsers) are affected?

I am on Mac OS 10.6.6, but I think all would be affected.
